vba - Microsoft Visual Basic 运行时错误 91

Question

当它到达 Cells.Find 时，它会给出运行时错误“91”
“对象变量或未设置 block 变量”。

Sub find_highlight()

w = "12:00:00 AM"

Cells.Find(What:=(w), After:=ActiveCell, LookIn:=xlFormulas, _
LookAt:=xlPart, SearchOrder:=xlByRows, SearchDirection:=xlNext, _
MatchCase:=False).Activate
 Range("B:B").Select
With Selection.Interior
    .ColorIndex = 6
    .Pattern = xlSolid
    .PatternColorIndex = xlAutomatic
  End With
End Sub

Answer 1

始终使用 Option Explicit在你的模块中声明所有变量类型

始终使用变量限定对象

直接处理对象(避免 .Select 或 .Activate )

您的 Find 中的语法已关闭称呼。无需包装变量 w在括号中。

(1 到 3 是最佳实践，但不是必需的。遗漏可能会产生意想不到的结果)。

Option Explicit

Sub find_highlight()

Dim ws As Worksheet
Set ws = Sheets("Sheet4") 'change as needed

Dim w As String 'maybe Date?
w = "12:00:00 AM"

Dim rng As Range, sFA  As String, rngFull As Range

Set rng = ws.Cells.Find(What:=w, After:=ActiveCell, LookIn:=xlFormulas, _
           LookAt:=xlPart, SearchOrder:=xlByRows, SearchDirection:=xlNext, _
           MatchCase:=False)

sFA = rng.Address

Do 'load all cells where w exists into range

    If Not rng Is Nothing And rngFull Is Nothing Then
        Set rngFull = rng
    ElseIf Not rng Is Nothing Then
        Set rngFull = Union(rng, rngFull)
    End If

    Set rng = ws.Cells.FindNext(rng)

Loop Until rng Is Nothing Or rng.Address = sFA

'highlight all cells found
With rngFull.Interior
    .ColorIndex = 6
    .Pattern = xlSolid
    .PatternColorIndex = xlAutomatic
End With

rngFull.NumberFormat = "mm/dd/yyyy" 'format as date -> change as needed


End Sub
